It features a 3\/8 inch cutting diameter, a 5\/8 inch length of cut, and a 4-flute, single-end configuration with a 30-degree helix angle. The AlTiN coating — marketed under the Ti-NAMITE-A designation — provides excellent heat resistance and tool life in ferrous and high-temperature alloy applications. Manufactured from micrograin carbide, the 31259 holds tight diameter tolerances and is suited for production environments where consistent performance and edge retention matter. Licensed HVAC and plumbing tradespeople do not typically install this product; it is purchased and used by machinists, tool-and-die shops, and CNC operators.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for milling steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. Its stub-length profile and right-hand cut and flute direction make it a practical choice for standard CNC machining centers and manual mills where rigidity is a priority. The variable index geometry helps reduce chatter and harmonic vibration during full-slot or side-milling operations, extending tool life and improving surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for improved hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN (Ti-NAMITE-A) coating rated for steel, stainless steel, cast iron, high-temp alloys, aluminum, and hardened materials\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eStub-length profile maximizes rigidity in tight-clearance setups\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.0000 \/ -0.0020 inches for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a properly sized collet or end mill holder and torque the retention nut to the equipment manufacturer specification. Verify runout with a dial indicator before beginning production cuts, as excessive runout accelerates edge wear and degrades surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN \/ Ti-NAMITE-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00035 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.125 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31259\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51733690712370,"sku":"31259","price":78.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e34157cbfb078ff89fdb079667e7fb57.jpg?v=1788758257","url":"https:\/\/voomisupply.com\/products\/sgs-31259-square-end-mill-3-8-inch-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
